RESUMO

Background: Communication difficulties in aphasia can result in social isolation, challenges with interpersonal relationships, emotional changes, inability to return to work, and lack of independence. Therefore, intervention is essential particularly in the context of functional communication for persons with aphasia (PwAs). Studies have also indicated that quality of communication life (QoCL) is a valid measure of the impact of communication difficulty on quality of life. Objective: To estimate the relationship between communication intervention and QoCL in individuals with expressive aphasia. Methods and Material: Twenty PwAs were divided into two groups: group I individuals had undergone at least 3 months of speech and language intervention whereas group II individuals did not have any formal communication intervention. Tamil version of the QoCL scale was administered for all participants. Statistical analysis was carried out using Mann-Whitney U test and Spearman's rho correlation coefficient. Results: Individuals with speech and language intervention in group I had higher scores in overall QoCL domains as well as in overall QoL when compared to group II. The results of correlation analysis indicated that individuals with greater therapy duration had significantly high scores. Conclusions: The results prove that communication intervention is necessary for PwAs to improve QoCL and can be used to raise awareness of its importance. The findings can also guide treatment planning, counseling the PwA, and caregivers. It also indicates the importance of using patient-related outcome measures during the intervention process.

RESUMO

BACKGROUND: Speech entrainment (SE), the online mimicking of an audio-visual speech model, has been shown to increase speech fluency in individuals with non-fluent aphasia. One theory that may explain why SE improves speech output is that it synchronizes functional connectivity between anterior and posterior language regions to be more similar to that of neurotypical speakers. OBJECTIVES: The present study tested this by measuring functional connectivity between 2 regions shown to be necessary for speech production, and their right hemisphere homologues, in 24 persons with aphasia compared to 20 controls during both free (spontaneous) speech and SE. METHODS: Regional functional connectivity in participants with aphasia were normalized to the control data. Two analyses were then carried out: (1) normalized functional connectivity was compared between persons with aphasia and controls during free speech and SE and (2) stepwise linear models with leave-one-out cross-validation including normed functional connectivity during both tasks and proportion damage to the left hemisphere as independent variables were created for each language score. RESULTS: Left anterior-posterior functional connectivity and left posterior to right anterior functional connectivity were significantly more similar to connectivity of the control group during SE compared to free speech. Additionally, connectivity during free speech was more associated with language measures than connectivity during SE. CONCLUSIONS: Overall, these results suggest that SE promotes normalization of functional connectivity (i.e., return to patterns observed in neurotypical controls), which may explain why individuals with non-fluent aphasia produce more fluent speech during SE compared to spontaneous speech.

RESUMO

OBJECTIVE: Group treatment enables people with aphasia to practise communication skills outside the typical clinician-patient dyad. While there is evidence that this treatment format can improve participation in everyday communication, there is little evidence it impacts linguistic abilities. This project aimed to investigate the effects of 'typical' group treatment on the communication skills of people with aphasia with a focus on word retrieval in discourse. METHODS: Three people with aphasia took part in a 6-week group therapy programme. Each week focused on a different topic, and three topics also received a home programme targeting word retrieval. The six treated topics were compared with two control topics, with regard to language production in connected speech. Semistructured interviews were collected twice prior to treatment and twice following the treatment and analysed using (a) word counts; (b) the profile of word errors and retrieval in speech; (c) a measure of propositional idea density, and (d) perceptual discourse ratings. RESULTS: Two participants showed no significant improvements; one participant showed significant improvement on discourse ratings. CONCLUSIONS: This study provides limited support for group treatment, leading to improved communication as measured by semistructured interviews, even when supplemented with a home programme. We suggest that either group treatment, as implemented here, was not an effective approach for improving communication for our participants and/or that outcome measurement was limited by difficulty assessing changes in connected speech.

RESUMO

BACKGROUND: To observe the effect of low-frequency repetitive transcranial magnetic stimulation (rTMS) on patients with nonfluent aphasia after stroke. MATERIALS AND METHODS: Thirty patients were divided into control, rTMS, and 2 times a day low-frequency rTMS (2rTMS) groups, and all 3 groups had intensive speech therapy (ST). Patients were assessed by western aphasia battery (WAB) scale. The spontaneous language, listening comprehension, retelling, and naming were scored, respectively. The expression of brain-derived neurotrophic factor (BDNF) in peripheral blood was detected by enzyme-linked immunosorbent assay. RESULTS: There was significant difference in aphasia quotient after treatment in the 3 groups. The values of the 4 dimensions in the WAB score of the rTMS group were higher than those in the control group. The WAB scores in the 2rTMS group were higher than those in the rTMS group. After 2 weeks treatment, the BDNF levels in the rTMS group and the 2rTMS group were significantly higher than those in the control group. Four weeks later, the 2rTMS group was significantly increased compared with the control group and the rTMS group. CONCLUSIONS: Low-frequency rTMS combined with conventional ST treatment can effectively improve the language function of patients with nonfluent aphasia after stroke. Two times a day low-frequency rTMS therapy combined with conventional ST treatment can improve the language function of patients with nonfluent aphasia after stroke more effectively and it also promote the expression of BDNF more effectively, thereby improving nerve repair and protecting brain tissue.

RESUMO

Augmented input is the strategy of supplementing expressive language with visuographic images, print, gestures, or objects in the environment. The goal of augmented input is to facilitate comprehension of spoken language. The purpose of this study was to evaluate the relative effectiveness of two different augmented input conditions in facilitating auditory comprehension of narrative passages in adults with aphasia. One condition involved the communication partner (clinician) of the adult with aphasia actively pointing (AI-PP) out key content words using visuographic supports. The second condition involved no active pointing (AI-NPP) by the communication partner (i.e., attention was not drawn to the visuographic supports). All 12 participants with aphasia listened to two narratives; one in each condition. Auditory comprehension was measured by assessing participants' accuracy in responding to 15 multiple-choice cloze-type statements related to the narratives. Of the 12 participants, seven gave more accurate responses to comprehension items in the AI-PP condition, four gave more accurate responses in the AI-NPP condition, and one scored the same in both conditions. These differences were not statistically significant (p > 0.05). Communication-partner-referenced augmented input using combined high-context and PCS symbol visuographic supports improved response accuracy for some participants. Continued research is necessary to determine partner involvement with and frequency of augmented input that improve auditory comprehension.

RESUMO

OBJECTIVE:: To collect data to estimate the sample size of a definitive randomized controlled trial to evaluate the effects of Melodic Intonation Therapy in post-stroke nonfluent aphasia. DESIGN:: A randomized, crossover, interventional pilot trial. SETTING:: Departments of Neurology and Rehabilitation from a university general hospital. PARTICIPANTS:: Stroke survivors with post-stroke nonfluent aphasia. INTERVENTIONS:: Patients randomized to group 1 had treatment with Melodic Intonation Therapy first (12 sessions over six weeks) followed by no treatment; the patients in group 2 started active treatment between three and six months after their inclusion in the study, serving as waiting list controls for the first phase. MAIN MEASURES:: The Communicative Activity Log (CAL) questionnaire and the Boston Diagnostic Aphasia Examination (BDAE) were evaluated at baseline, and at six and 12 weeks. RESULTS:: Twenty patients were included. Four of the patients allocated to group 2 crossed over to group 1, receiving the treatment at first. Intention-to-treat analysis: after adjustment for baseline scores, the mean difference in the CAL evaluation from baseline in the treated group was 8.5 points (95% confidence interval (CI), 0.11-17.0; P = .043), with no significant change in any of the BDAE sections. Per-protocol analysis showed similar results with a clear treatment effect ( P = .043) on the CAL. CONCLUSION:: Melodic Intonation Therapy might have a positive effect on the communication skills of stroke survivors with nonfluent aphasia as measured by the CAL questionnaire. A full-scale trial with at least 27 patients per group is necessary to confirm these results.

RESUMO

Aphasia is considered as an acquired neurological disorder of communication, which is characterised by the symptoms on all levels of language dysfunction. The current study was planned to explore the outcomes of script training in a patient with Broca's aphasia through quantitative approach using a single-subject-multiple-baseline research design across behaviours. The probes were obtained during the baseline, treatment, maintenance and generalisation phases for tracking the spoken use of scripted content. All the probes were transcribed verbatim and no value of Cohen's Kappa Coefficient (K) was below 0.61, indicating robust inter-rater reliability. The subject learned all six scripts successively and over 80% of mastery level on all dependent variables was achieved. The largest effect size, above 10.1, was reported for the percent of intelligible scripted words (PISW). Script training was found to be an effective therapy for rejuvenating lost communication of patients with severe Broca's aphasia.

RESUMO

PURPOSE: Compare the results in naming tasks of after-stroke aphasic individuals divided into active and placebo groups pre- and post-transcranial direct current stimulation. METHODS: A double-blind, randomized, controlled study conducted with 14 individuals. Patients underwent five 20-min sessions with stimulation of 2mA's on consecutive days. The cathode was placed over the Broca's homologous area and the anode was placed over the supraorbital region of the left hemisphere. Boston and Snodgrass naming tasks were assessed before and after the stimulation sessions and the results were compared between the groups. RESULTS: No significant results were observed for sequences 1 and 2 in the Snodgrass test. The Boston test results indicated significant difference related to mean time for correct responses with strategy. CONCLUSION: The results suggest that simultaneous transcranial direct current stimulation (anodic and cathodic) is a method that can improve the rehabilitation of patients with anomic and Broca's aphasia after stroke, and that language strategies should be considered in the analysis of naming task responses.


OBJETIVO: Comparar os resultados nas tarefas de nomeação de pacientes afásicos após AVC dos grupos ativo e controle. MÉTODO: Estudo duplo-cego, randomizado controlado com 14 pacientes. Os indivíduos foram submetidos a cinco sessões de 20 minutos de 2 mA em dias consecutivos. O catodo foi posicionado na área homóloga à Broca e o anodo sobre a região supraorbital do hemisfério esquerdo. Os testes de Boston e Snodgrass foram aplicados e os resultados comparados entre os grupos. RESULTADOS: Não houve resultados significativos para as sequências 1 e 2 no teste do Snodgrass. No teste de Boston, os dados indicaram uma diferença significativa para o tempo médio de acertos com estratégia. CONCLUSÃO: Os resultados sugerem que a ETCC simultânea (anódica e catódica) é um método que pode auxiliar a reabilitação de pacientes com afasia do tipo anômica e de Broca, após AVC, e que as estratégias linguísticas deveriam ser consideradas nas análises das respostas dos testes de nomeação.

RESUMO

Purpose: Social models of aphasia rehabilitation emphasize the importance of supporting identity renegotiation, which can be accomplished in part through personal narrative construction. The purpose of this study was to examine the experiences of persons who had engaged in a project to coconstruct personal narratives about life with aphasia. Method: Qualitative interviews were conducted with 3 participants with aphasia who completed a 4-week personal narrative coconstruction project, which included preadministration and postadministration of the Communication Confidence Rating Scale for Aphasia (Cherney & Babbitt, 2011). Results were analyzed using interpretative phenomenological analysis. Results: Three themes were revealed: (a) More than a story: It changed my life validated the idea that the narrative coconstruction process supported a positive view of identity; (b) A positive experience captured the participants' enjoyment in coconstructing and sharing their story; (c) Hope engendered by the coconstruction experience empowered participants with new levels of confidence not only in their communication skills but also in themselves. Conclusions: This study provided insight into the experience of coconstructing personal narratives using a structured protocol. Participants experienced the project as a positive, meaningful opportunity to actively contemplate their life and look forward. The study has implications for clinicians considering support of identity renegotiation in aphasia rehabilitation.

RESUMO

Purpose: Current computer technologies permit independent practice for people with cognitive-communicative disorders. Previous research has investigated compliance rates and outcome changes but not treatment fidelity per se during practice. Our aim was to examine adherence to procedures (treatment fidelity) and accuracy while persons with aphasia independently practiced word production using interactive, multimodal, user-controlled, word-level icons on computers. Method: Four persons with aphasia independently practiced single-word production after stimulation via user-initiated interactions in 3 conditions: (I) auditory stimulus with static representational drawing; (II) auditory stimulus with synchronized articulation video; and (III) users' choice between the 2 prior conditions. Sessions were video-recorded for subsequent analysis, which established emergently refined behavioral taxonomies using an iterative, mixed-methods approach. Results: In independent practice, users only sometimes adhere to modeled behaviors, other times improvising novel behaviors. The latter sometimes co-occurred with successful productions. Differences in success rates were noted between Conditions I and II across behaviors with Condition II generally favored. In Condition III, participants tended to choose the stimulus that resulted in highest success rates. Conclusions: During independent practice with technology, persons with aphasia do not necessarily comply with clinicians' practice instructions, and treatment fidelity does not determine success. Autonomy and choice in practice may reveal unanticipated dimensions for computerized aphasia treatment.

RESUMO

BACKGROUND: Patients with brain lesions and resultant chronic aphasia frequently suffer from depression. However, no effective interventions are available to target neuropsychiatric symptoms in patients with aphasia who have severe language and communication deficits. OBJECTIVE: The present study aimed to investigate the efficacy of 2 different methods of speech and language therapy in reducing symptoms of depression in aphasia on the Beck Depression Inventory (BDI) using secondary analysis (BILAT-1 trial). METHODS: In a crossover randomized controlled trial, 18 participants with chronic nonfluent aphasia following left-hemispheric brain lesions were assigned to 2 consecutive treatments: (1) intensive language-action therapy (ILAT), emphasizing communicative language use in social interaction, and (2) intensive naming therapy (INT), an utterance-centered standard method. Patients were randomly assigned to 2 groups, receiving both treatments in counterbalanced order. Both interventions were applied for 3.5 hours daily over a period of 6 consecutive working days. Outcome measures included depression scores on the BDI and a clinical language test (Aachen Aphasia Test). RESULTS: Patients showed a significant decrease in symptoms of depression after ILAT but not after INT, which paralleled changes on clinical language tests. Treatment-induced decreases in depression scores persisted when controlling for individual changes in language performance. CONCLUSIONS: Intensive training of behaviorally relevant verbal communication in social interaction might help reduce symptoms of depression in patients with chronic nonfluent aphasia.

RESUMO

About a quarter of stroke patients worldwide suffer serious language disorders such as aphasias. Most common symptoms of Broca's aphasia are word naming disorders which highly impact verbal communication and the quality of life of aphasic patients. In order to recover disturbances in word retrieval, several cueing methods (i.e. phonemic and semantic) have been established to improve lexical access establishing effective language rehabilitation techniques. Based on recent evidence from action-perception theories, which postulate that neural circuits for speech perception and articulation are tightly coupled, in the present work, we propose and investigate an alternative type of cueing using silent articulation-related visual stimuli. We hypothesize that providing patients with primes in the form of silent videos showing lip motions representative of correct pronunciation of target words, will result in faster word retrieval than when no such cue is provided. To test our prediction, we realize a longitudinal clinical virtual reality-based trial with four post-stroke Broca's patients and compare the interaction times between the two conditions over the eight weeks of the therapy. Our results suggest that silent visuomotor cues indeed facilitate word retrieval and verbal execution, and might be beneficial in lexical relearning in chronic Broca's patients.

RESUMO

BACKGROUND: In this study we investigated the neurolinguistic and neuroimaging characteristics of post-stroke motor aphasia patients. The effects of acupuncture on cortex activation by using magnetic resonance imaging (MRI) in patients with motor aphasia were also studied. METHODS: In this study 43 patients with motor aphasia after stroke were assessed according to Clinical Rehabilitation Research Center aphasia examination (CRRCAE) for linguistic evaluation and MRI and computed tomography (CT) were used for the analyses of brain lesions. The MRI imaging data were also examined using statistical parametric mapping (SPM8) software. Cortex activation images during acupuncture were analyzed using generalized linear model analysis. RESULTS: The results of MRI and CT showed diverse brain lesion regions of post-stroke motor aphasia including the cortex, subcortex and cortex together with the subcortex. The language-related brain areas are activated by acupuncture including frontal, temporal, parietal and occipital lobes as well as insula, precuneus and other wide range of brain function areas as shown by MRI. CONCLUSIONS: Our study showed that the brain lesion regions in post-stroke motor aphasia were not completely consistent with the classical motor speech center. By using MRI our study results suggest that the formation of cognitive language may be involved with the cortical-subcortical functional networks. Acupuncture may be useful for treatment of motor aphasia after stroke.

RESUMO

Based on findings for overlapping representations of bilingual people's first (L1) and second (L2) languages, unilingual therapies of bilingual aphasia have been proposed to benefit the untrained language. However, the generalisation patterns of intra- and cross-language and phonological therapy and their neural bases remain unclear. We tested whether the effects of an intensive lexical-phonological training (LPT) in L2 transferred to L1 word production in a Persian-French bilingual stroke patient with Broca's aphasia. Language performance was assessed using the Bilingual Aphasia Test, a 144-item picture naming (PN) task and a word-picture verification (WPV) task. Electroencephalography (EEG) was recorded during PN and WPV in both languages before and after an LPT in French on a wordlist from the PN task. After the therapy, naming improved only for the treated L2 items. The naming performance improved neither in the untrained L2 items nor in the corresponding items in L1. EEG analyses revealed a Language x Session topographic interaction at 540 ms post-stimulus, driven by a modification of the electrophysiological response to the treated L2 but not L1 items. These results indicate that LPT modified the brain networks engaged in the phonological-phonetic processing during naming only in the trained language for the trained items.

RESUMO

BACKGROUND: There is increasing interest in the application of cortical stimulation (CS) as an adjuvant strategy in aphasia rehabilitation. Epidural CS, although more invasive than other methods, can provide high-frequency ipsilesional stimulation with greater spatial specificity. OBJECTIVE: We review methods and results of a phase 1 study of epidural CS in combination with rehabilitation therapy in aphasia and provide new objective and self-report data collected between 6 and 21 months after the end of treatment. METHODS: Eight stroke survivors with nonfluent aphasia received intensive language therapy, 3 hours a day, for 6 weeks. Four participants also underwent surgical implantation of an epidural stimulation device that was activated only during therapy sessions. Behavioral data were collected before treatment, at the end of treatment, and at 6 and 12 weeks after the end of treatment. Of the 8 participants, 7 also participated in the longer-term follow-up visit. RESULTS: Changes in objective scores from baseline were larger in investigational participants than controls at all assessments, including the longer-term follow-up visit. Satisfaction ratings and ratings of overall improvement by investigational participants and their companions were more varied than those of the controls, but all indicated that they would recommend the investigational treatment to others with aphasia. CONCLUSIONS: Improvements were generally maintained for at least 12 weeks posttreatment and possibly as long as 21 months posttreatment. Epidural CS is a potentially safe, feasible adjunctive intervention for persons with chronic nonfluent aphasia that spares the ventral premotor cortex and warrants further investigation.

RESUMO

The presence or absence of generalization after treatment can provide important insights into the functional relationship between cognitive processes. The aim of the present study was to investigate the relationship between the cognitive processes that underlie sentence comprehension and production in aphasia. Using data from seven participants who took part in a case-series intervention study that focused on noncanonical sentence production [Stadie et al. (2008). Unambiguous generalization effects after treatment of noncanonical sentence production in German agrammatism. Brain and Language, 104, 211-229], we identified patterns of impairments and generalization effects for the two modalities. Results showed (a) dissociations between sentence structures and modalities before treatment, (b) an absence of cross-modal generalization from production to comprehension after treatment, and (c), a co-occurrence of spared comprehension before treatment and generalization across sentence structures within production after treatment. These findings are in line with the assumption of modality-specific, but interacting, cognitive processes in sentence comprehension and production. More specifically, this interaction is assumed to be unidirectional, allowing treatment-induced improvements in production to be supported by preserved comprehension.

RESUMO

OBJECTIVE: To investigate the therapeutic effect of repetitive transcranial magnetic stimulation (rTMS) and speech and language therapy (SLT) on the improvement of performance on the Korean-version of the Western Aphasia Battery (K-WAB) in post-stroke non-fluent aphasic patients. METHODS: Twenty post-stroke, non-fluent aphasic patients were enrolled and assigned to one of two groups: a case group (n = 10) or a control group (n = 10). Participants were recruited from the inpatient clinic of the Physical and Rehabilitation Medicine Department of Bundang Jesaeng General Hospital from March 2011 to January 2012. The case group received rTMS and SLT and the control group received SLT; both groups received these therapies for four weeks. Language functioning was evaluated using K-WAB before and after treatment. RESULTS: There were no significant differences between the groups' baseline characteristics and initial values (p > 0.05). After four weeks of therapy, there were significant improvements in repetition and naming in the case group (p < 0.05). However, there was no significant improvement in the control group (p > 0.05). CONCLUSIONS: rTMS combined with SLT can be an effective therapeutic method for treating aphasia in post-stroke non-fluent aphasic patients, although additional controlled and more systemic studies should be conducted.

RESUMO

Given the increasing rates of stroke and our aging population, it is critical that we continue to foster innovation in stroke rehabilitation. Although there is evidence supporting cognitive rehabilitation in stroke, the set of cognitive domains effectively addressed to date represents only a small subset of the problems experienced by stroke survivors. Further, a gap remains between investigational treatments and our evolving theories of brain function. These limitations present opportunities for improving the functional impact of stroke rehabilitation. The authors use a case example to encourage the reader to consider the evidence base for cognitive rehabilitation in stroke, focusing on four domains critical to daily life function: (1) speech and language, (2) functional memory, (3) executive function and skilled learned purposive movements, and (4) spatial-motor systems. Ultimately, they attempt to draw neuroscience and practice closer together by using translational reasoning to suggest possible new avenues for treating these disorders.

RESUMO

Broca's aphasia is the most challenging communication deficit in stroke. Left inferior frontal gyrus (IFG), a key region of the mirror-neuron system, gets lesioned in Broca's aphasia. Mirror therapy (MT), a form of action-observation, may trigger the mirror neurons. The aim of this study was to report a case of poststroke subject with Broca's aphasia, who exhibited an inadvertent and significant improvement in speech after MT for the paretic upper limb. The 20-month old stroke patient underwent MT through goal-directed tasks. He received a total absence of spontaneous speech, writing, and naming. After 45 sessions of task-based MT for the upper limb, he showed tremendous recovery in expressive communication. He had fluent and comprehensive communication; however, with a low pitch and minor pronunciation errors. He showed a substantial change (from 18/100 to 79/100) on the Communicative Effective Index, particularly, on items such as expressing emotions, one-to-one conversation, naming, and spontaneous conversation.
